disable deploying wayland platform plugins

wayland platform plugins currently deployed in the CI are built on ubuntu focal and only compatible with wayland prior to 1.20. Attempting to run the appimage on modern wayland DEs results in a symbol lookup error and failure to run #18598 so disable for now until a workaround is implemented in a future release

effectively a revert of #13781
